54-Pro A, 54-Pro Vario (Illustration D + E ); 54-Pro Vario Plus (Illustration A + D + E ); Emergency Stopping; Movement Drive - Sabo 54-PRO A Livret D'entretien

long as the mower has not been lowered to the ground again, both your hands must be
on the top part of the bar.
CAUTION
Hold the starter cable handle firmly when starting. The handle may otherwise slip
out of your hand. Risk of injury!
IMPORTANT
The motor only operates when the safety control bracket is pressed against the
upper part of the handlebar. As soon as the safety control bracket is released,
this returns to its original position under spring force, the motor brake is
actuated, and the motor and blade come to stop within three seconds.
NOTE
This engine has a ReadyStart system: This system has a temperature-controlled
®
automatic choke. The engine runs with optimum power at maximum speed, which is
required for a clean cutting pattern (engine speed = blade speed).

54-PRO A, 54-PRO VARIO (Illustration D + E )

– Push and hold the safety control bar (2) on the top tube (3) D .
– Slowly pull the starter cable (4) until resistance is felt, then rapidly pull it out E –

54-PRO VARIO PLUS (Illustration A + D + E )

– Open the ventilation valve (1) in the fuel filler cap A .
– Open the fuel cock A .
– Press the safety control bar (2) on to the upper part of the handle (3) and hold in
place D .
– Slowly pull the starter cable (4) until resistance is felt; then rapidly pull it out E –
the engine begins to run, slowly recoil the cable.
All models
Switching off the engine (Illustration F + A )
– Release the safety control bar (1) F .
– Close the fuel tap A (only on model with additional tank).

Emergency stopping

NOTE
Before every mowing job, make sure that the safety control bar for the engine
brake and the engine drive control bar are working perfectly:
– when the safety control bar is released, the engine and cutter bar must come
to a standstill within three seconds.
– when the engine drive control bar is released, the machine must come to a
standstill immediately.
If this is not the case, please consult your nearest authorised workshop.

11 MOVEMENT DRIVE

Operating the rear wheel drive (Illustration G )

The rear wheel drive is switched on and off by means of the drive control handle (1) on
the top guide tube (2) when the engine is running:
– Pull and hold the drive control bar = mower moves.
– Release the drive control bar = mower stops (0-position).
NOTE
The rear wheels click when the mower is pushed forwards.
54-PRO VARIO, 54-PRO VARIO PLUS

Adjusting the speed (Illustration H )

IMPORTANT
The speed may only be adjusted when the engine is running in order to avoid
damage!
NOTE
Mowing at high speed leads to poor cutting pattern or collection result. Always
adapt the speed to the prevailing conditions. For longer grass sections, a slower
moving speed should be selected.
The driving speed is set using the rotary knob mounted on the left.
– The knob can be turned in both directions for speed adjustment, so that the
required driving speed can be set. The arrow on the knob indicates the driving
speed.
– Position "Hare" = fast (max. speed)
– Position "Tortoise" = slow (min. speed)
All models

Grass collector

12 OPERATION WITH GRASS COLLECTOR

WARNING
When operating the equipment with a collecting bag, the bag must be completely
assembled and in technically perfect condition.
IMPORTANT
Make sure that the chute (1) R1 is not bent when handling the collector.
During mowing ensure that the collector is emptied in good time. The turbo indicator on
the collector will indicate when the collector should be emptied. A deflector (available as
an accessory from dealers under the Order No. SA592) can also be fitted in place of the
grass collection bag.
Turbo signal (shows when the grass collector is full)
(Illustration J + K )
There is an indicator on the top of the collector that shows whether the collector is
empty or full:
– The collector indicator inflates if the collector is empty and during the mowing J .
– If the collector is full, the indicator collapses; once this happens, stop mowing
immediately and empty the collector K .
IMPORTANT
If the fabric of the grass collector is very dirty the turbo indicator will not inflate –
in this case, clean the fabric immediately. The grass collector will only collect
grass perfectly if it is permeable to air.
IMPORTANT
Do not clean the grass collector with hot water!

Emptying the grass collector (Illustration L )

– Switch off engine.
– Lift ejection flap.
– Unhinge the full grass collector from the mower at the carrying strap – the ejection
flap closes automatically.
– Empty the collector thoroughly whilst holding it by the carrying strap and the
moulded handle on the bottom.

Operation without grass collector

WARNING
When mowing without grass collector the ejection flap on the mower housing
must always be closed (flap down).

13 MOWING

Mowing on slopes

NOTE
The mower can be used on banks and slopes with a gradient of up to 46% (25°
angle). Any steeper slopes can lead to engine damage.
For safety reasons, however, we urgently recommend you do not exploit this
theoretical performance potential. Always make sure you have a firm stance.
Manually guided lawnmowers should never be used for slopes with a gradient in
excess of 26% (15° angle of slope). Stability may be lost!
